47 00:03:01,995 --> 00:03:05,665 Wikidata is a sister project of Wikipedia, 48 00:03:06,385 --> 00:03:11,500 and it's a free knowledge base that is based on facts and references 49 00:03:11,500 --> 00:03:15,630 that both machines and humans can edit and reuse. 50 00:03:16,860 --> 00:03:21,202 Wikidata is linked to other resources via IDs, 51 00:03:21,202 --> 00:03:24,235 which we call "external identifiers." 52 00:03:25,505 --> 00:03:29,110 Those resources could also be linked to other databases 53 00:03:29,110 --> 00:03:31,880 and even interlinking back to Wikidata. 54 00:03:32,710 --> 00:03:36,650 When all of these resources are open access, as Wikidata is, 55 00:03:37,445 --> 00:03:42,025 then we call that data network "Linked Open Data." 56 00:03:44,165 --> 00:03:46,840 Wikidata is part of the Wikimedia projects, 57 00:03:46,840 --> 00:03:50,600 and like all of its sister projects, Wikidata is multilingual, 58 00:03:50,600 --> 00:03:52,492 and it has no language barriers. 59 00:03:54,045 --> 00:03:57,995 The data in Wikidata is released under the CC0 license, 60 00:03:58,375 --> 00:04:01,975 meaning Wikidata's data is public domain 61 00:04:01,975 --> 00:04:06,560 and has no exclusive intellectual property rights applied to it. 62 00:04:07,820 --> 00:04:12,370 Wikidata items are made up of statements and references, 63 00:04:12,835 --> 00:04:14,841 and I'm sure we are going to be talking more 64 00:04:14,841 --> 00:04:16,959 about statements and references 65 00:04:17,395 --> 00:04:18,785 in the later sessions. 66 00:04:20,900 --> 00:04:25,380 Finally, Wikidata is made for humans and machines, 67 00:04:25,870 --> 00:04:28,162 and it's available for everyone to use, 68 00:04:28,162 --> 00:04:31,405 whether on the Wikimedia projects or outside of it. 69 00:04:33,415 --> 00:04:34,485 Alright. 70 00:04:34,485 --> 00:04:36,237 What is so cool about Wikidata, 71 00:04:36,237 --> 00:04:38,480 and why is Wikidata so useful?

91 00:05:39,770 --> 00:05:40,785 (Mohammed) Absolutely. 92 00:05:40,785 --> 00:05:45,448 I'm happy to show you a few examples of the reuse of Wikidata's data. 93 00:05:47,585 --> 00:05:52,195 First, it's a game called Guessr, 94 00:05:54,280 --> 00:05:59,420 and you can find it by going to <i>guessr.blinry.org</i> 95 00:06:02,375 --> 00:06:06,088 This game tests our knowledge of geography 96 00:06:06,088 --> 00:06:09,335 by guessing the locations of rundown Wikidata items 97 00:06:10,700 --> 00:06:15,360 that has a geolocation statement on the item. 98 00:06:17,060 --> 00:06:18,228 This image, 99 00:06:19,425 --> 00:06:21,485 coming from Wikimedia Commons-- 100 00:06:21,485 --> 00:06:25,195 the game is asking me to guess the location of the image, 101 00:06:26,560 --> 00:06:28,541 and it provides me with a map. 102 00:06:28,850 --> 00:06:31,020 I can go ahead and make a guess. 103 00:06:31,950 --> 00:06:32,950 Er... 104 00:06:33,880 --> 00:06:35,900 Not entirely sure where this is, 105 00:06:36,145 --> 00:06:38,428 but I would make a random guess here, 106 00:06:38,428 --> 00:06:43,585 just so you have a feel of how it works. 107 00:06:44,360 --> 00:06:45,654 If I make a guess, 108 00:06:45,654 --> 00:06:51,532 and it says, "You are 1,724 kilometers off." 109 00:06:51,532 --> 00:06:52,680 (laughing) 110 00:06:52,680 --> 00:06:53,920 Alright. 111 00:06:54,265 --> 00:06:59,366 Okay. The next example of reuse of Wikidata data 112 00:06:59,366 --> 00:07:01,725 I would like to show you is Crotos. 113 00:07:04,360 --> 00:07:09,234 Crotos is a search and display engine for visual artwork 114 00:07:09,234 --> 00:07:11,890 powered by Wikidata and Wikimedia Commons. 115 00:07:13,045 --> 00:07:16,409 You can use Crotos to search for and display artwork 116 00:07:16,409 --> 00:07:18,948 by Louis Morère, for example, 117 00:07:19,564 --> 00:07:24,000 if they do exist on Wikidata and on Wikimedia Commons. 118 00:07:24,620 --> 00:07:28,942 When we searched for artwork by Louis Morère, 119 00:07:29,250 --> 00:07:32,435 we did find a few that exist on Wikidata, 120 00:07:32,845 --> 00:07:37,105 and I can go ahead and click on them, and take a closer look. 121 00:07:38,205 --> 00:07:43,555 My last example is the case of the reuse of Wikidata's data 122 00:07:44,050 --> 00:07:47,110 to create Infoboxes on Wikipedia. 123 00:07:48,365 --> 00:07:52,735 Here is an example of an Infobox on Dagbani Wikipedia 124 00:07:53,045 --> 00:07:56,388 that is entirely created from Wikidata's data. 125 00:07:59,220 --> 00:08:00,224 (Léa) Alright. 126 00:08:00,224 --> 00:08:02,115 Let's have a look at Wikidata now. 127 00:08:02,115 --> 00:08:04,093 Can you explain to us a little bit 128 00:08:04,093 --> 00:08:08,045 how the information is organized on Wikidata? 129 00:08:10,515 --> 00:08:16,295 (Mohammed) First, concepts on Wikidata are contained on pages called "items." 130 00:08:19,040 --> 00:08:22,830 This is an example of an item 131 00:08:23,488 --> 00:08:26,818 with an item label <i>Haruna Iddrisu</i>, 132 00:08:27,685 --> 00:08:33,495 with an item identifier Q1621154, 133 00:08:34,365 --> 00:08:36,420 which is unique to it. 134 00:08:38,480 --> 00:08:43,295 On each item, you would notice what we call the "termbox." 135 00:08:44,815 --> 00:08:50,235 The termbox is this box that contains the Language, Label, 136 00:08:50,235 --> 00:08:54,277 Description, and the Aliases-- Also known as. 137 00:08:57,630 --> 00:09:00,776 The Labels are in different languages, 138 00:09:01,795 --> 00:09:04,360 and they exist for each item. 139 00:09:05,055 --> 00:09:09,815 The Descriptions are used to describe 140 00:09:09,815 --> 00:09:13,195 what the item is about in the simplest form. 141 00:09:15,200 --> 00:09:17,747 In this case, Haruna Iddrisu 142 00:09:18,475 --> 00:09:21,532 is described as a "Ghanaian politician." 143 00:09:24,295 --> 00:09:28,241 The Aliases are other labels 144 00:09:28,887 --> 00:09:31,081 that this individual or this concept 145 00:09:33,303 --> 00:09:34,461 could be known as. 146 00:09:34,655 --> 00:09:36,913 For example, Haruna Iddrisu 147 00:09:37,435 --> 00:09:38,539 could also be known 148 00:09:38,539 --> 00:09:43,365 as "Gangdu" or "Loya Aduna" in Dagbani. 149 00:09:46,230 --> 00:09:50,640 Now, underneath the termbox are the Statements. 150 00:09:54,855 --> 00:09:57,595 There are a lot of statements on this item. 151 00:10:02,260 --> 00:10:06,340 On Wikidata, things are modeled based on triples. 152 00:10:08,785 --> 00:10:12,663 The three different parts of a triple make up a statement. 153 00:10:13,795 --> 00:10:18,139 Here, we have an item identifier, which has this Q ID-- 154 00:10:18,139 --> 00:10:20,870 Q16211514. 155 00:10:21,507 --> 00:10:24,237 There's a property <i>instance of,</i> 156 00:10:25,046 --> 00:10:27,496 and a value, which is <i>human.</i> 157 00:10:28,375 --> 00:10:29,425 As you can see, 158 00:10:29,885 --> 00:10:31,905 each statement on an item page 159 00:10:31,905 --> 00:10:34,042 links to a property, 160 00:10:35,364 --> 00:10:37,302 and assigns it a value. 161 00:10:39,430 --> 00:10:42,770 A triple can be read like a sentence in plain English, 162 00:10:43,175 --> 00:10:44,973 as a statement containing 163 00:10:45,755 --> 00:10:47,099 subjects, 164 00:10:47,099 --> 00:10:48,598 predicates, 165 00:10:49,175 --> 00:10:50,512 and objects. 166 00:10:51,580 --> 00:10:52,808 In this example, 167 00:10:53,324 --> 00:10:57,420 Haruna Iddrisu is an <i>instance of</i> a <i>human</i>. 168 00:11:00,295 --> 00:11:04,247 Another statement could be, for example, 169 00:11:06,900 --> 00:11:09,000 the position that they held. 170 00:11:10,660 --> 00:11:13,544 Here, we can see that they are 171 00:11:13,544 --> 00:11:17,515 a "Member of the 7th Parliament of the 4th Republic of Ghana." 172 00:11:18,295 --> 00:11:20,715 So that is another statement on its own. 173 00:11:23,200 --> 00:11:27,192 Now, aside from the basic triple model, 174 00:11:27,192 --> 00:11:31,852 we can also add extra details to contextualize Wikidata statements. 175 00:11:35,305 --> 00:11:39,930 We can do so by adding <i>qualifiers</i> and <i>references.</i> 176 00:11:41,970 --> 00:11:45,040 Qualifiers, they allow statements 177 00:11:45,040 --> 00:11:49,825 to be expanded on and annotated beyond what can be expressed. 178 00:11:50,285 --> 00:11:51,528 Example, 179 00:11:51,528 --> 00:11:56,445 for this Statement, Haruna Iddrisu-- <i>position held:</i> 180 00:11:56,957 --> 00:12:00,220 <i>Member of the 7th Parliament of the 4th Republic of Ghana,</i> 181 00:12:00,680 --> 00:12:05,745 we can add a simple property value pair <i>parliamentary group,</i> 182 00:12:06,525 --> 00:12:09,185 which is a property on its own, as you would notice. 183 00:12:10,605 --> 00:12:14,748 And then the value for that property would be the NDC, 184 00:12:14,748 --> 00:12:17,136 the <i>National Democratic Congress.</i> 185 00:12:17,600 --> 00:12:20,680 This allows us to add a bit more context 186 00:12:21,090 --> 00:12:25,004 to what party they actually were an MP of. 187 00:12:26,155 --> 00:12:31,761 Then, we may also add references, or as many references as we want 188 00:12:31,761 --> 00:12:33,750 to point to specific sources 189 00:12:34,210 --> 00:12:37,115 that back up the data provided in the Statement, 190 00:12:37,115 --> 00:12:41,258 that they were, yes, indeed, once a member 191 00:12:41,258 --> 00:12:43,855 of the sovereign Parliament of the 4th Republic of Ghana 192 00:12:44,210 --> 00:12:47,310 in the parliamentary group, the NDC. 193 00:12:47,730 --> 00:12:49,337 If I click on that reference, 194 00:12:49,337 --> 00:12:51,875 I would see that it has a <i>reference URL,</i> 195 00:12:52,140 --> 00:12:57,842 which points us to the website that tells us 196 00:12:57,842 --> 00:13:00,604 that they indeed held this position. 197 00:13:01,352 --> 00:13:03,923 Then we also have another property,

00:13:12,414 --> 00:13:15,965 should be supported by a verifiable source of information. 201 00:13:15,965 --> 00:13:21,950 If you can indeed provide that as references for your statement, 202 00:13:21,950 --> 00:13:23,190 that would be great. 203 00:13:23,470 --> 00:13:28,840 Beneath the regular statements are external Identifiers. 204 00:13:30,425 --> 00:13:32,987 These are external systems, 205 00:13:32,987 --> 00:13:36,520 such as Databases or Authority Control files, 206 00:13:36,730 --> 00:13:40,504 that also have information about this person, Haruna Iddrisu. 207 00:13:40,860 --> 00:13:43,380 There's an <i>OpenSanctions ID.</i> 208 00:13:43,725 --> 00:13:46,315 There's a <i>Prabook ID,</i> 209 00:13:46,315 --> 00:13:48,475 and also a <i>Freebase ID.</i> 210 00:13:49,845 --> 00:13:51,505 I can click on any of these, 211 00:13:52,190 --> 00:13:55,668 and those should take me to those other resources 212 00:13:55,668 --> 00:14:00,940 that have information about Haruna Iddrisu, the person. 213 00:14:07,925 --> 00:14:10,575 In Wikidata, the <i>instance of</i> property, 214 00:14:10,575 --> 00:14:14,120 represented by the property ID P31, 215 00:14:14,930 --> 00:14:16,840 is one of the fundamental properties 216 00:14:16,840 --> 00:14:20,790 that plays a crucial role in organizing and categorizing information. 217 00:14:22,755 --> 00:14:26,301 For example, this item, Haruna Iddrisu, 218 00:14:26,685 --> 00:14:29,965 is a specific example of a definition of a "human." 219 00:14:31,700 --> 00:14:36,884 Therefore, the property <i>instance of</i> P31 serves as the backbone 220 00:14:36,884 --> 00:14:42,281 for linking and categorizing all search items of people as humans. 221 00:14:43,525 --> 00:14:46,140 Other fundamental Wikidata properties exist, 222 00:14:46,850 --> 00:14:52,646 such as <i>subclass of</i> with the property ID P279; 223 00:14:53,780 --> 00:14:57,240 <i>part of</i> with the property ID P361; 224 00:14:57,755 --> 00:15:01,855 and <i>has part</i> with the property ID P527. 225 00:15:02,715 --> 00:15:06,095 We'll be discussing more of these in the later session. 226 00:15:06,900 --> 00:15:11,806 (Léa) Could you show us again this very first Statement <i>instance of</i>? 227 00:15:12,550 --> 00:15:14,182 What exactly does it mean? 228 00:15:14,182 --> 00:15:15,901 It seems important. 229 00:15:16,935 --> 00:15:19,578 (Mohammed) In Wikidata, the <i>instance of</i> property, 230 00:15:19,578 --> 00:15:23,017 represented by the property ID P31, 231 00:15:24,040 --> 00:15:26,000 is one of the fundamental properties 232 00:15:26,000 --> 00:15:29,780 that plays a crucial role in organizing and categorizing information. 233 00:15:31,725 --> 00:15:33,055 For example, 234 00:15:33,055 --> 00:15:35,423 this item, Haruna Iddrisu, 235 00:15:35,797 --> 00:15:39,278 is a specific example of a definition of a "human." 236 00:15:40,740 --> 00:15:44,083 Therefore, the property <i>instance of</i> P31 237 00:15:44,720 --> 00:15:47,835 serves as the backbone for linking and categorizing 238 00:15:47,835 --> 00:15:51,090 all search items of people as humans. 239 00:15:52,535 --> 00:15:55,385 Other fundamental Wikidata properties exist, 240 00:15:55,920 --> 00:16:01,700 such as <i>subclass of</i> with the property ID P279; 241 00:16:02,800 --> 00:16:06,260 <i>part of</i> with the property ID P361"; 242 00:16:06,835 --> 00:16:10,935 and <i>has part</i> with the property ID P527. 243 00:16:12,675 --> 00:16:13,990 (Léa) Alright. 244 00:16:14,340 --> 00:16:17,125 Now, I see all of this information in English, 245 00:16:17,125 --> 00:16:19,940 but what if I want to see it in another language? 246 00:16:19,940 --> 00:16:21,281 Can I do it? 247 00:16:22,395 --> 00:16:24,803 (Mohammed) You can see this data in another language 248 00:16:24,803 --> 00:16:28,555 by clicking the language selector next to your username. 249 00:16:30,255 --> 00:16:31,615 So if I click on it, 250 00:16:31,980 --> 00:16:35,675 I will be able to see the content of this item 251 00:16:36,107 --> 00:16:37,999 in French, for example. 252 00:16:41,085 --> 00:16:42,785 Then, you would notice 253 00:16:42,785 --> 00:16:45,925 that the interface changes as well, 254 00:16:46,635 --> 00:16:50,085 and I can switch back to English, if I want to. 255 00:16:51,540 --> 00:16:52,550 (Léa) Cool. 256 00:16:52,550 --> 00:16:54,770 I would love to start editing Wikidata now. 257 00:16:54,770 --> 00:16:56,345 Is there a place where I can go 258 00:16:56,345 --> 00:16:59,285 to do some test edits without breaking anything? 259 00:16:59,915 --> 00:17:02,395 (Mohammed) A great way to practice editing in Wikidata 260 00:17:02,395 --> 00:17:05,775 and not break anything or at least annoy other editors 261 00:17:06,315 --> 00:17:09,065 is to use the Wikidata Sandbox. 262 00:17:09,930 --> 00:17:12,196 The Sandbox itself is an item 263 00:17:12,196 --> 00:17:15,011 where you can go and add statements of all kinds, 264 00:17:15,011 --> 00:17:17,790 even if those statements don't really make any sense. 265 00:17:18,285 --> 00:17:19,876 Let's take a look. 266 00:17:22,245 --> 00:17:24,525 This is the Wikidata Sandbox, 267 00:17:25,660 --> 00:17:27,600 and you would indeed notice 268 00:17:27,820 --> 00:17:31,520 that it resembles any typical Wikidata item 269 00:17:33,315 --> 00:17:36,436 with labels, and descriptions, and statements, 270 00:17:36,436 --> 00:17:39,328 except that these don't really make sense 271 00:17:39,645 --> 00:17:41,695 because, of course, they are used for testing. 272 00:17:44,408 --> 00:17:50,425 You can edit a Statement, for example. 273 00:17:51,735 --> 00:17:55,415 Instead of saying this is an <i>instance of</i> a "human," 274 00:17:55,415 --> 00:18:00,309 you could say this is an <i>instance of</i> a "river body" 275 00:18:01,900 --> 00:18:03,342 or a "river." 276 00:18:05,340 --> 00:18:06,998 Then I click on <i>Publish.</i> 277 00:18:10,645 --> 00:18:13,219 I can edit these other statements 278 00:18:14,842 --> 00:18:17,230 and add references to them, even. 279 00:18:17,230 --> 00:18:20,290 I could even add a new statement from scratch. 280 00:18:21,930 --> 00:18:24,240 I can do that by scrolling 281 00:18:24,550 --> 00:18:28,615 to the very end of the existing statements, 282 00:18:29,285 --> 00:18:31,946 you would find <i>add statement.</i> 283 00:18:31,946 --> 00:18:33,639 If I click on it, 284 00:18:34,501 --> 00:18:39,401 it gives me a chance to enter a property and then later on a value. 285 00:18:39,960 --> 00:18:41,890 Let's say I wanted to add 286 00:18:44,955 --> 00:18:46,958 the sex or gender 287 00:18:46,958 --> 00:18:50,554 if this item were about a human. 288 00:18:52,855 --> 00:18:55,097 I will start typing "sex" or "gender," 289 00:18:55,097 --> 00:18:56,715 and if I'm lucky, 290 00:18:57,380 --> 00:18:58,743 that suggest that-- 291 00:18:59,264 --> 00:19:02,355 gives me some options, and I can see <i>sex or gender.</i> 292 00:19:02,355 --> 00:19:06,285 Once I click on it, I'll be able to include the gender. 293 00:19:08,835 --> 00:19:12,760 Once I include the value for that property <i>sex or gender,</i> 294 00:19:13,850 --> 00:19:15,583 I would click on <i>Publish,</i> 295 00:19:16,964 --> 00:19:18,888 and then it gets saved. 296 00:19:23,105 --> 00:19:27,185 Those little information signs you saw are called "constraints." 297 00:19:29,350 --> 00:19:33,370 Let's see if we can find a constraint violation on this page. 298 00:19:36,355 --> 00:19:37,635 This is an example 299 00:19:38,535 --> 00:19:39,995 of an information sign, 300 00:19:40,375 --> 00:19:45,715 and they provide guidelines for editors to ensure data quality and consistency 301 00:19:46,040 --> 00:19:47,900 when modeling Wikidata items. 302 00:19:49,340 --> 00:19:54,495 Clicking on it reveals details, I mean, advice and hints 303 00:19:54,950 --> 00:19:57,615 about the constraints applied to that property, 304 00:19:57,995 --> 00:20:00,255 and how you can go about fixing them. 305 00:20:01,195 --> 00:20:03,460 (Léa) Alright. Sounds good. 306 00:20:03,460 --> 00:20:05,346 So, the Sandbox is the right place 307 00:20:05,346 --> 00:20:08,398 to go to keep practicing a little bit, 308 00:20:08,398 --> 00:20:11,520 and editing, and seeing what's happening. 309 00:20:12,595 --> 00:20:15,255 Tell me, can I also edit Wikidata on mobile? 310 00:20:16,595 --> 00:20:19,400 (Mohammed) Yes. You can edit Wikidata on mobile, 311 00:20:19,410 --> 00:20:22,334 although the mobile interface is currently not perfect. 312 00:20:22,930 --> 00:20:24,210 At the moment, 313 00:20:24,210 --> 00:20:26,448 you can edit the Termbox, 314 00:20:27,448 --> 00:20:29,732 and you can also add sitelinks, 315 00:20:32,998 --> 00:20:36,505 but you cannot edit statements for now. 316 00:20:36,950 --> 00:20:39,195 However, the way you could do that, 317 00:20:39,720 --> 00:20:43,160 if you are on mobile, as I am on currently, 318 00:20:43,590 --> 00:20:45,383 you would have to scroll down 319 00:20:45,383 --> 00:20:48,585 to the very end of the item 320 00:20:50,632 --> 00:20:54,901 and then request the desktop site for the item 321 00:20:55,790 --> 00:20:58,113 by clicking on <i>Desktop.</i> 322 00:20:58,910 --> 00:21:00,130 Once you do that, 323 00:21:02,055 --> 00:21:04,235 you can switch to Landscape Mode, 324 00:21:05,495 --> 00:21:09,035 so you can get a good view of the items and the click button. 325 00:21:10,440 --> 00:21:11,625 (Léa) Alright. 326 00:21:12,020 --> 00:21:14,375 So it seems that when I'm editing Wikidata, 327 00:21:14,375 --> 00:21:15,940 and I click on <i>Publish,</i> 328 00:21:15,940 --> 00:21:20,215 my edits are directly added to the website. 329 00:21:20,845 --> 00:21:24,253 Is that right, or is there anyone checking my edits 330 00:21:24,253 --> 00:21:25,803 before they get published? 331 00:21:27,540 --> 00:21:30,424 (Mohammed) Yes.
